Modified Files:
	src/sys/kern: vfs_subr.c

Log Message:
Fix a variety of kernel panics related to unchecked export data:
1. sa_len was not properly checked.
2. sa_family was not properly checked [even used as an array index!]
3. we only know about inet4 and inet6, so make sure that the corresponding
   data is valid before using it.
4. keep reference counts of addresses used (is that necessary?)
